Junkyard Gem: 1981 Cadillac Eldorado with V8-6-4 engine

Skyrocketing fuel prices caused by geopolitical events in 1973 and 1979 led to gas lines, federal fuel economy requirements, and an increasing reluctance on the part of American car shoppers to buy big, thirsty Detroit luxury machines. General Motors had pulled off some amazing technological feats in the past — the small-block Chevrolet V8 engine and Hydramatic transmission being two extraordinarily successful ones — and so Cadillac's bosses figured that a combination of computer wizardry and clever mechanical engineering would give the 368-cubic-inch Cadillac V8 a cylinder-deactivation system and resulting superior fuel economy. Here's a very rare example of one of those 1981 Cadillacs, found in a California self-service wrecking yard. The idea behind the V8-6-4 was that computer-controlled solenoids would physically disengage the rocker arms for one or two cylinders on each engine bank under low-load conditions, converting the engine from a 368-cube V8 to a 276ci V6 or 184ci V4 (that's 6.0, 4.5 or 3.0 liters, respectively, for the metric-system aficionados among us). This sort of variable-displacement magic is commonplace today, but it was science-fiction stuff in 1981. An "MPG Sentinel" display on the dash would let the driver know how many cylinders were active at the moment, and the car would get Chevy Citation fuel economy with Cadillac luxury. The V8-6-4 was the standard engine in all 1981 Cadillacs (except for the Seville, which had the troubled Oldsmobile diesel engine as the base powerplant and the V8-6-4 as an option). Unfortunately, the V8-6-4 worked about as well as the Oldsmobile diesel: very poorly. Within a few years, most owners of these engines had disconnected the rocker-deactivation solenoids and just drove their cars as regular full-time V8s. This one has the snazzy "Cabriolet Roof Treatment" option, which boasted "textured elk grain" vinyl and could be had in one of 17 available colors. Front-wheel drive gave the early-1980s Eldorado plenty of interior space, despite its more proletarian Olds Toronado origins, and these velour-covered seats made for very comfortable road trips. The price tag started at $17,550, or about $51,650 in 2019 dollars. The 1981 Imperial went for $18,311, and that car was based on the same platform as the lowly Plymouth Volare. Meanwhile, A BMW 733i cost $28,945 and a new Toyota Cressida a mere $11,599. The 1981 Cadillacs were just a little too much ahead of their time, it turned out.

GM recalling another 2.7 million vehicles in five separate campaigns

The recalls keep rolling in from General Motors, evidently keen to avoid repeating the mistakes of the ignition-switch debacle and clean house. This time they're all coming at once, with five separate recalls announced together covering approximately 2.7 million vehicles.
The largest of the five actions involves over 2.4 million units of the previous-generation Chevrolet Malibu and Malibu Maxx, Pontiac G6 and Saturn Aura in order to fix brake light wiring harness, which have been found to be susceptible to corrosion. The recall is separate from the 56k Aura sedans which GM recently recalled over faulty shift cables, not to mention the previous massive recall of 1.3 million vehicles - some of them the same models - but appears to have resulted from the National Highway Traffic Safety Administration investigation that started with the G6 almost a year ago.
The second-largest campaign involves the 2014 Chevy Malibu, specifically those fitted with GM's 2.5-liter engine and stop/start system, approximately 140,000 examples of which has been found to have problematic brakes. The issue does not appear to be connected to the recall of 8k Malibu and Buick LaCrosse sedans (also involving brake woes) which we reported upon last week. Four crashes have been reported in such models, but GM admits it's not yet clear if the problem was a contributing factor in the accidents.

Cadillac sprinkles changes around its 2022 lineup

Cadillac is doing its best to keep the model-year-update train running, making incremental changes to the CT4, CT5, XT4, XT5, and XT6 for 2022. We'll start with the change coming to the entire Cadillac range, that being the addition of the automaker's Smart System package of nine driver assistance aids. The nine features are: Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Safety Alert Seat, Rear Park Assist, Rear Vision Camera, vehicle diagnostics, Teen Driver, and Rear Seat Reminder. After that, the CT4 and CT5 will gain the option of Super Cruise 1 and Super Cruise 2 on Sport and Premium Luxury trims. Super Cruise availability on the XT6 to follow at some point during the model year, but since the XT6 is built on GM's previous electrical architecture, its version of Super Cruise will lack some features such as Automated Lane Change. Also inside the vehicles, it's been reported that Inteluxe will be the new name for leatherette seating across the lineup.  Taking each model starting with the CT4, GM Authority says the compact sedan will lose its Dark Blue Moon Metallic, Evergreen Metallic, and Velocity Red exterior colors. They'll be replaced by Blaze Orange Metallic (pictured), which is reserved for the Sport, CT4-V, and CT4-V Blackwing, and Electric Blue and Dark Emerald Frost, which can only be optioned on the CT4-V and CT4-V Blackwing, and the latter color will have limited availability. The CT5 gets one of those new premium exterior hues, Blaze Orange Metallic. It will be available on the CT5 Sport alone. The base 350T models powered by the 2.0-liter turbocharged four-cylinder also had their fuel economy figures updated recently. The rear-driver gains another mile per gallon in the city and combined, the all-wheel driver gains one mpg in the city and loses one mpg on the highway, according to the EPA. The XT4 drops the premium exterior colors Shadow Metallic, Garnet Metallic, and Autumn Metallic. They are replaced by Galactic Gray Metallic, Latte Metallic, and Rosewood Metallic, all of which will add $625 to the MSRP and be available throughout the model lineup. Cadillac Society reports that NFC capability falls away next year, the tech deemed outdated. The refreshed XT4 that had been expected next year is now thought to arrive for the 2023 model year.
